Title:RedHat Security Advisory RHSA-2008:0965

The remote host is missing updates announced in
advisory RHSA-2008:0965.

Lynx is a text-based Web browser.

An arbitrary command execution flaw was found in the Lynx lynxcgi: URI
handler. An attacker could create a web page redirecting to a malicious URL
that could execute arbitrary code as the user running Lynx in the
non-default Advanced user mode. (CVE-2008-4690)

Note: In these updated lynx packages, Lynx will always prompt users before
loading a lynxcgi: URI. Additionally, the default lynx.cfg configuration
file now marks all lynxcgi: URIs as untrusted by default.

A flaw was found in a way Lynx handled .mailcap and .mime.types
configuration files. Files in the browser's current working directory were
opened before those in the user's home directory. A local attacker, able to
convince a user to run Lynx in a directory under their control, could
possibly execute arbitrary commands as the user running Lynx. (CVE-2006-7234)

All users of Lynx are advised to upgrade to this updated package, which
contains backported patches correcting these issues.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
